Linear induction motor

摘要

A linear induction motor comprising an inductor with a multiphase concentrated winding, a magnetic circuit, including groups of laminated cores, and an electrically conducting secondary element disposed within the inductor and separated by an air gap from the legs of the laminated cores whose laminations are directed perpendicular to the direction of movement of the magnetic field. In each of said groups, the laminated cores have their axes of symmetry positioned in a plane perpendicular to the direction of movement of the magnetic field and shifted circumferentially relative to one another by a given angle alpha , while the axes of symmetry of the laminated cores of a subsequent group are shifted relative to the axes of symmetry of the laminated cores of a preceding group by an angle alpha /2.
